Speed studies are conducted to determine the 85th percentile speed and identify reasonable driver behavior for a particular stretch of roadway. The speed study is one part of an engineering and traffic investigation — a nationally accepted guideline for setting speed limits.

The survey team in the field also identifies and considers other factors — including traffic crash data, traffic volumes, roadside development, roadway configuration and condition, number of intersections and driveways, sidewalks, and any other factors that may influence all types of road users.
